-// This file implements a variety of small optimizations for calls to specific
-// well-known (e.g. runtime library) function calls. For example, a call to the
-// function "exit(3)" that occurs within the main() function can be transformed
-// into a simple "return 3" instruction. Any optimization that takes this form
